Abstract
Introduction. The gills are, for the fish, the most important organ for the transportation and regulation
of ionic and osmotic gradients, and for the balance
acid-base, the excretion of nitrogen wastes and the
metabolism of circulating hormones, becoming the
center of the physiological responses to internal and
environmental changes. Objective. To make a document to register the structure, the vascularization
and the main cells of this ephitelium, and its relation
with ionic transportation for maintaining its homeostasis, in order to sustain the role of the ionic regulation in the homeostasis of fish, keeping in mind that
these physiological mechanisms can be a reason
to fail or to succeed in the fish breeding activities.
Selection criteria for the bibliography. Classic authors on the fish physiology field were revised, plus
many articles produced from research works and
revisions from the last ten years. These materials
were published especially in English and Portuguese. Results. There is an unexplored field concerning the mechanisms that maintain the homeostasis
in fish. The work for our species is yet to be done.
The new molecular tools could help to elucidate the
contributions of many membrane transportation processes to the acid-base balance regulation, to the
ionic transportation and to the excretion of metabolites associated with these processes. Challenges.
To integrate different disciplines in order to obtain a
clear image of how gills work and how the processes
mentioned before determine the well being of fish.
